Calculate the power dissipated by the cold bulb

Reference no: EM13535443

A 60-W incandescent bulb with a tungsten filament is connected to a 120-V power supply. When it operates, its temperature increases by 3000?C. If the temperature coefficient of resistivity of tungsten is 4.5×10-3, the power dissipated by the cold bulb is:
